Enabling OAM Remote Loopback

After enabling OAM remote loopback on a port, you can send loopback frames from the port to a
remote port and then observe how many of these loopback frames are returned. In this way, you can
calculate the packet loss ratio on the link, thus evaluating the link performance.
